Thermal Imaging Thermometers are compact, have a focus-free lens and simple navigation for easy one-handed operation, tough enough for rugged field use. Temperature range is -4°-482°F (-20°-250°C) ±2% or 2°C and batteries last about four hours with quick charging available from the included AC charger. Models are rated to withstand shock values to 25g. Thermal image enhancement adds key details from the visible spectrum camera to the entire infrared image on the 3in color LCD screen, displaying accurate thermal gradients and visible details.
All models have 45° x 34° field of view and 320x240 pixel resolution for the image. Enhanced MA-776 and MA-778 models feature better infrared resolution, selectable measurement modes and picture-in-picture display, which superimpose a thermal image over a visible spectrum photo. Up to 500 sets of infrared, visual and MSX images can be stored as .jpeg files in internal memory for later analysis and reporting. The unmatched manufacturer`s warranty offers 10 year coverage on the detector, 5 year on the battery and 2 years parts and labor.

How do small silkworms start sleeping?
Sleep treatment is an important technical operation in the sericulture process. Generally can be divided into three periods of pre-sleep treatment, sleep protection and foraging treatment. Pre-sleep treatment should pay attention to the timely increase of sleep network, timely mention of Saccharomyces sang. The body color of the first instar silkworm was mostly fried and the individual had attained the age of sleeping. The silk color of the 2nd instar silkworm was milky, and the skin was tense and shiny. A few silkworms would sleep for a suitable period of time. The 3rd instar silkworm appeared to sleep. Silkworm is suitable for screening. The temperature during sleep is 0.5-1.0°C lower than that of mulberry, and the wet and dry difference is 2～3°C in the early middle of sleep (Sang-Sang to the found silkworm), and the wet-dry difference is 1.5 in the middle and late period of sleep (before silkworm is found to feed). ~2°C. Keep quiet in sleep, the light should not be too strong, avoid polarizing and wind. Because the upper and lower temperatures of the silkworm shelf are high and low, the position of the silkworm cocoon needs to be exchanged, and it is usually exchanged 1 to 2 times a day, so that the development of the silkworm becomes uniform. For the first time after the first time, the larvae are called for food (or called opening leaves). The appropriate period of feeding is mainly based on the color and appetite of the head of the silkworm. Usually, silkworms begin to have appetite after 2 to 3 hours after molting, and the head of the silkworm turns light brown. When the performance of seeking food is proper for foraging, it is easy to make the silkworm grow unevenly. The mulberry must be fresh and ripe and tender. The amount of mulberry should be properly controlled. For the first time, the amount of food given is 80% of the pre-harvest age. It is better to control the food.
